NBB-04R Networked Audio Receiver

NBB-04T Networked Audio Transmitter

Overview:

The NBB-04R receives 4 channels of analog audio and converts them into Dante networked audio

stream which in turn can be received by other Dante-enabled devices such as digital audio console

or DAW; While the NBB-04T, in contrast, transmits 4 channels of analog audio converted from

Dante networked audio stream which is distributed from other Dante-enabled devices.

Both NBB-04R and NBB-04T are equipped with two RJ-45 Ethernet ports so that several NBB-

04R/NBB-04T can be cascaded, i.e. in daisy-chaining, in the same network link. Also both NBB-

04R and NBB-04T can be powered by either PoE from Ethernet switch or 48V from external power

adapter.

Features:

Dante-enabled networked Audio Receiver (NBB-04T) and Transmitter (NBB-04T)

Streaming audio in robust standard Ethernet cable (a.k.a., Digital Snake)

Easily organize and expand network topology with Ethernet switches

Uncompressed 24-bit PCM coding with sample rate up to 96KHz

Two RJ-45 ports make Daisy-chain cascading feasible

Gain or Attenuate control for each channel

Phantom power engagement control per channel (NBB-04R)

A signal clip indicator for all inputs (NBB-04R)

XLR Combo sockets for both XLR and TRS phone plugging (NBB-04R)

Routing and other configuration are set with Dante Controller software

Description: The NBB-04R and NBB-04T adopt Audinate Dante networking technology for audio transceiving, and are very network friendly with unlimited flexibility in topology of deployment. They support up to Layer 3 of IEEE 802.3 network standard, enabling you to organize your audio network with the onthe-shelf Ethernet switches or to immediately transport streaming audio by taking advantage of your existing installed network facility with no hassle.

Getting Started Guide: Powering The NBB-04R and NBB-04T can be powered by either, PoE from Ethernet switch with PoE PSE capability, or 48V power adapter which should be included in your device package. It is O.K. for you to power your NBB-04R/NBB-04T with both PoE and 48V adapter simultaneously. However, since the operating voltage of PoE is usually higher than 48V, very likely your NBB-04R/NBB-04T will sink power only from PoE if you do so.

Setting Once your NBB-04R/NBB-04T is powered, you can configure your NBB-04R/NBB-04T by direct connecting it to your computer or via the Ethernet switch. That is to say that the NBB-04R/NBB04T can direct talk to your computer or via switch. See picture below for an illustration. All the routing assignment and device configuration are set via Dante Controller software which is available free from the following Audinate webpage, www.audinate.

Front Panel To accommodate all the variety of field installation, the front panels of NBB-04R and NBB-04T are equipped with rich control facilities as follows, 1. The Gain control knobs of NBB-04R can accommodate itself to accept all kind of sources with level from mic to line. 2. The +48V button to control whether to deliver phantom power to power source device or not. 3. The clip indicator flashes to warns audio technicians if any of inputs is overloaded. 4.

A default button on one of the side panels is used to restore the settings of NBB-04R/NBB-04T to factory default. Press and hold the switch when you powering up the device will restore the device to default state. Once you see both SYS and SYNC LEDs red, you can then re-power the device for the default settings to take effect. The cap of the default button is sunk to panel to avoid your accidentally triggering the action of default restoring.

Applications: Direct Connecting to Notebook or Console One of the beauty of Dante is that you do not need a DHCP server or router in between to establish all kind of communication among different Dante-enabled devices. You can even connect your UNiKA Dante-enabled devices to your computer or digital console without an Ethernet switch in between.
PAGE 8
Connecting via Ethernet Switch Once your audio network grows up to turn complex, you may want to add Ethernet switches in your audio network so that you can better manage the cabling among all your Dante-enabled devices. For a large-scale system, you may even have several Ethernet switches in your audio network. The switches, including the mini switch in UNiKA Dante-enabled devices, do cause propagation delay but fortunately every one of them only contribute delay in several tens of microseconds.
PAGE 9
Connecting via Switch with PoE PSE Capability Both NBB-04R and NBB-04T support to be powered by Ethernet PoE, so that you don't need a 48V wall adapter if your NBB-04R/NBB-04T direct connects to an Ethernet switch with PoE PSE capability. Also, you are allowed have have more than one console in your audio network, but keep in mind that only one of them can be set to be a clock master for the whole network. The clock master provides word clock for audio framing synchronization.
